Aty the back of the frame a stop bar is provided and the key levers are weighted at 31 to hold them normally against this stop barin order toeven up g the key-board, and this evenin action is independent of the weight of t e parallel bars, so that should a keybe operated call-V ing for the raising of a certain number of parallel bars includi those barsA common 0 to another letter containing a less number of elements, the tendency of destroying the balance of the key board and the evenness thereof will be removed by the employment of the overweighted key levers and the back stop. Each key lever is provided with an anvil 32 which works against the lower end of the comb bar or stem 24.

Punching 'mechanisme-The grouping ot the punches for perforating the tape 'is shown in Fig. 17, the upper row being the marking hole punches, the lower rou' the spacing hole punches, while the intermediate punches are for the feed holes, there being nine marking hole punches, ten spacing hole 5 punches and eleven feed hole punches. Fig. i7 is the chart of the group of punches for the international Morse double current sys-- tem. The American Morse code requires fewer punches than illustrated in Fig. 17, and the international cable code requires still fewer punches. It will be understood that my invention can be carried out vvithy either grouping of punches, the operating mecha nism being the 'same in each case, and my in- ..6 vention, therefore, is not limited to anyv particular code or grouping of punches, but

moreover, the constructon permits. Where requiredl` of a standard type of instrument with interchan cable letter combs to meet .0' the special di erences between the several systems. These punches are mounted lo slide vertically in a housing 33`being guided in a. top plate 34 thereof, and in the guide die-plate B5 arranged above the cutting-die L6' plate 36, the tape to be perforated passing throu h the channel or space between these die plates shown in Fins. 2 and 11. A slider 37 is movable ver-tica ly within the punch housing by pitman 37', operated as willv be hereinafter described, and this slider has slots on each side shown at 38 in 2 and 4, and cross pins 39 extending across the upr endsof' the slots, these slots recrving interlocking bars or pins 40 which, when projected inwardly in any predetermined groups', as selected by the combs, will select and'connect the proper punches, to repre sent the letter, with the slider, so that when the slider is moved down, it will carry with it the punches selected to pcrforate the tape with the desired number and grouping of' holes to represent the character correspondw ing to the key operated. For this purpose each marking-hole and spacinghole punch 65 is provided with an 4eye or opening to re ceive the interlocking pin, or bar, as shown in Fig. Only those marking and spacingr hole punches are carried down by the slider which are stiflceted by the interlocking bara, but at each downward movement of the slider all of the feed hole punches are cai'- ried dou n to perforate the tape `with the full number ol" feed holes. For this purpose the central feed hole punches are provided each with a boss or shoulder 4l being held in a 75 recess in the slider by the bottoni plate 4-:3 screwed in place, and as the u cr wall of this recess hears on the shoulilus of the feed-hole punches, the whole series of saifl feed-hole punches will be carried down ai each operation, whether the character printcd be made up of few or many of the mark ingr and spacing punches, and if' of the former and the feed of the talnl is short, some of the feedshole punches will simply pass 86 idly through thc feed-holes which 'were punched at the previous o aeration. By thev use of these feedhclc unclies which operate at. each depression, o the slider, l :un en ablcd to employ a maximum feed key marked Max on the keyboard, so that when a maximum feed of tape is required-` or when a length of tape is required having only central feed-holes punched therein, in stead. of depressing the space key live time,A (when ity is arranged for double acing), or eleven times (when it is arrange for single spacing), the max key is operated, causing, at 'one operation eleven holes to be cut, and the tape fed forward that distance, as will behereinaftcr described.

The space key or bar is shown at b, and when this' is depressed all of the feedhole punches will he carried down to perfor-ate the paper, but instead of the maximum feed 105 of tape taking place a shorter feed ot tape, just referred to of one or two holes, takes place for spacingr between words.

The interlocking bars 40 operate in two sets, one at the front and the other at the no rear of the punch housing, those of the front set bein ivoted to pivoted levers 43 and those o' tie rear set boing pivoted to bell crank levers 44. The levers fl. are connected by links 45 to bell crunk lovers 46, and these 115 bell crank lewis are cpm-ated by springs 44 and by selecting pins 7 passing throu h a plate 4S, and cnffagfd by the parallel se ecting bars 28, and as before described, these parallel bars are .selected and operated in 120 certain groups by the teeth or proJec/tions on the com bars Q7, according to which key is operated.

There are twenty-nine parallel selectingY bars as sbownin Figs. 7 and El, twenty of 125 these controlling the formation of the let ters and nine controlling the tape feed action.

On release of the roduoedeed key, the carrier. plate, with selecting pins, re sumes its nomini. position under the action of spring 139.

Increase feed me#tontons-WAS shown in Figs. 15 and. 16, I employ en :increase feed key for the purpose oi' increasing the space between successivo characters. This mecha mism consists of u key ninrlred. Ine, und when this is pressed, the, carrier plate for the selecting pins would be given a movement to the lett instead of to the right, so that the reverse eteet from that just de scribed in eonnocdon with the reduce-feed .lrey would take plone, nninely: the feed of the tope would be increased above the nurmal. rlhis increase-feed key is also combined with the reduce feed key red as shown in said figure, so that the carrier plate muy be moved eitlnnl 'Way for either of the above effects.

For holding the carrier pluto in normal position, and for returning it to suidlnorin ol position When'moved either Way there4 from, I provide the two levers 110H one bearing on each side of a rojeetion' on the carrier plate, Suid levers being ntossed by springs liti* to .hold them normally against stop pins, and thus set the carrier plate in normal position. If 'the plate is moved either way, the lever 110l on that ,side will yield to permit the movement, but ne soon as 'the key lever is released, the carrier plate will resume its normal position under the action. of the spring 11W.

In combination punches, n star-feed -Wheel for the tope, e ratchet wheel, n pawl, means for operating the pnwi to turn the ratchet, comprising en oscillating feed-gin der, a cheek. tooth lever connected with the feed irder, a detent foi; the checktooth lever r preventing rebound and over feed, and means for releasing said detent con-- trolled from the keys, substantially :is described.

22. In combination punches., e. stur-feed Wheel for feeding tape, n feed-girder with connections for operating the ster feed wheel therefrom, electroqnagnetie means for operating the feed =f girder, electro-magnetic means for operating the linches, u Contact' ke)7 for controlling saidJ electro-magnetic means, n revcrseehcclr-tocth lever for arresting the feed, a detent for preventing rebound and overfeed, and u connection for releasing the detent consisting of the pin bearing on the detent and the lever operated from the contact key for moving said pin,

substantially es described.

`,23. In combination in :ippnrntns of the clsiss described, punches, tape feed mecha nism, differential stop feed bars, keys., con nections between the und the stop feed bars including selecting pine, :1nd n carrier therefore, connections between seid selectin g menue insand the stop feed bars, said connections ing selected by the said selec-,ting pins, n cnrrler for said selecting pins, and un increase-feed key for shifting .said carrier to make the selecting ins select a sto feed bar for n longer feeA than normal, su stantinlly as described.

24. In combination in apparatus of the class described, punches, tape feed mechanism, character keys with means controlled thereby for operating the unches and the tope feed mechanism, n re nce-feed key and an increase-feed ke with connections controlled thereby or reducing or increasing the tape feed when the character keys are operated, substantially as described.
